Networking with Business Communications Manager
The Business Communications Manager is a key building block in creating your communications
network. It interoperates with many devices, including the Meridian 1 system and H.323 devices.
The Business Communications Manager system can be connected to devices through multiple IP
networks, as well as through the PSTN. Multiple Business Communications Manager systems also
can be linked together on a network of VoIP trunks and/or dedicated physical lines. Refer to
Chapter 8, “Typical network applications using MCDN,” on page 147.
The Business Communications Manager can be connected to a LAN through a LAN card, to a
WAN through a WAN card, and to a PSTN through trunk media bay modules, as shown for
Business Communications Manager A in the above diagram. Through these networks, the system
accesses other systems and network equipment connected to the network.
